Anemia is one type of red blood cell disorder. A lack of the mineral iron in your blood usually causes this disorder. Your body needs iron to produce the protein hemoglobin, which helps your red blood cells carry oxygen from your lungs to the rest of your body.
Well, they should, because fire behavior is the result of, and is affected by, the method and the amount of heat energy transfer within the fire environment. There is a fourth method by which fire spreads that is of great concern to firefighters.
Radiant heat pre-heats the fuel in front of the fire, making the fuel even more flammable. For every 10Ë slope, the fire will double its speed. For example, if a fire is travelling at 5 km per hour along flat ground and it hits a 10Ë slope it will double in speed to 10 km per hour up the hill. By increasing in speed the fire also increases in intensity, becoming even hotter. The opposite applies to a fire travelling downhill. The flames reach less fuel, and less radiant heat pre-heats the fuel in front of the fire. For every 10Ë of downhill slope, the fire will halve its speed. Fires tend to move more slowly as the slope decreases.
